10 Website Videos Mistakes and How to Solve Them

It should come as no surprise that video use on the internet is exploding. You can see the dramatic growth of video on the average site in this SpeedCurve blog post.

With the growth in video comes greater bandwidth use, which is not only costly for your IT budget, but for your visitors as well. Beyond the expense, there is the user experience to consider. The heavier the page, the longer it will take to load, and the greater likelihood visitors will abandon your site. Page load speed is also an important factor in SEO ranking, so clearly video is something we need to take seriously and get right. Video is challenging, presenting terms still unfamiliar to developers - like codecs, bitrate and adaptive bitrate streaming. As a result, mistakes are being made in video implementation.

Multi Codec Adaptive Bitrate Streaming

In Part I of this series, we discussed the optimal way to deliver progressive video streams, taking advantage of modern, efficient codecs. That approach works great for short-form videos (under 20 seconds) and for videos that are displayed at a low resolution (such as ads and previews). But what if you're delivering videos that are longer than 20 seconds for a higher-resolution experience? You can certainly still deliver them as a single file (progressive streaming), but you might run into issues, such as buffering or too high a resolution.

Video Optimization With the HTML5 <video> Player

Lack of experience and compression knowhow can cause significant user-experience problems. For instance, on a major retail site, I recently ran into a 48 MB video-hero banner. Pulling out the video and encoding it as an H.264 MP4 reduces the size to 1.9 MB. So, despite the desire for more video content, developers have not yet caught up to best practices. How do we get the best of both worlds without creating a disaster like the one above?

Automatically deliver the best image format to the browser

One of the main optimization challenges for website and mobile developers is how to display sufficiently high quality images to their visitors while minimizing the image file size. A smaller image file size can lead to faster load times, reduced bandwidth costs and an improved user experience. The problem is that reducing the file size too much may lead to a lower image quality and could harm visitor satisfaction. Delivering an optimized image with just the right balance between size and quality can be quite tricky.

Using smart-cropping for automatic art direction

Note: this article was originally published in Smashing Magazine.

Four years ago, Jason Grigsby asked a surprisingly difficult question: How do you pick responsive images breakpoints? A year later, he had an answer: ideally, we’d set responsive image performance budgets to achieve “sensible jumps in file size”. Cloudinary built a tool that implemented this idea, and the response from the community was universal: “Great! Now – what else can it do?” Today, we have an answer: art direction!

Plugin for Automatic Responsive Image HTML Code Generation

This is a guest post by Nicolas Hoizey, co-founder of Clever Age and creator of the Jekyll Cloudinary plugin. Nicolas’ plugin leverages Cloudinary’s image storage, optimization, resizing, and delivery infrastructures to automate responsive images in Jekyll-generated static sites. We think it’s the bee’s knees, and invited Nicolas to write a bit about the process and motivation behind it. Without further ado, here’s Nicolas.

Get More Out of HTML5 Video Tags with Cloud-Based Video Transcoding

Once upon a time, in long forgotten browser versions, getting a video into a website required creating and embedding Flash resources. But these days, all modern browsers support HTML5, including the HTML5 <video> tag, which means you’ve got a built-in video player that anyone can use.
